Apache Spark reassigned SPARK-28224:
------------------------------------
Assignee: Apache Spark
> Sum aggregation returns null on overflow decimals
> -------------------------------------------------
>
> Key: SPARK-28224
> URL: https://issues.apache.org/jira/browse/SPARK-28224
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Mick Jermsurawong
> Assignee: Apache Spark
> Priority: Major
>
> Given the option to throw exception on overflow on, sum aggregation of
> overflowing bigdecimal still remain null. {{DecimalAggregates}} is only
> invoked when expression of the sum (not the elements to be operated) has
> sufficiently small precision. The fix seems to be in Sum expression itself.
